The NDW100 is a 100 mile continuous trail run along the North Downs Way. The course travels from Farnham in the Surrey Hills to Ashford in Kent. Total climb of 11,000 feet.

The race begins in Farnham at the Western end of the North Downs. The course works its way through some of the best of the English countryside before traveling through the small village of Puttenham and on to Guildford. It then continues on to Ranmore Common before the steepest climb of the race up to the top of Box Hill. The trail then drops down the other side and back up to Reigate Hill, on through Merstham to Oxted and a further 8 miles to Knockholt Pound and the 50 mile point at the outermost edge of Greater London. The course then travels on through Wrotham and Holly Hill before crossing the Medway Bridge. The final 25 miles see runners travel South East towards Dover running the majority on trails, paying brief visits to the villages of Detling, Hollingbourne, Harrietsham and Charing before dropping down into Ashford and the finish at the Julie Rose Stadium. Race held under full UK Athletics Permit granted through the TRA (Permit Number 6634).

Course Markings

The course is marked by permanent national trail marker posts which come in different forms but most commonly display the acorn which is the key symbol and guide on the North Downs Way.

In addition to the fixed markers as above, the course will also be marked with red, white and silver reflective barrier tape, Centurion marker arrows and small amounts of orange chalk paint at major junctions. It is always possible that course markers may be removed or vandalised, in which case you will need to use the National Trail marker posts as the primary guide. There are a number of road crossings to negotiate, some of them are extremely busy. The road crossings will NOT be marshalled so runners need to remain vigilant and be extremely careful, particularly late in the race when energy is lagging. 

It is ultimately the runners responsibility to navigate the course successfully, with or without course markings. If you are in any doubt we strongly recommend that you take the time to recce the route before race day.

Please see the Course Notes Page here for further details.


Runners are permitted pacers from the Otford Crew Point at Mile 54.5. Pacers must travel on foot only. Runners are permitted multiple pacers throughout the last 50 miles but only one may travel with the runner at any one time.

The points at which a runner may be paced/ hand over pacers are listed on the crew page here


Runners are allowed to have a crew but may only have one crew vehicle at any one time out on course. The points at which a runner may be crewed, are listed on the crew page here. Crews will not be permitted to crew for their runner at any point other than those listed. 


There will be a team of race medics available throughout the duration of the weekend including race ambulances and static medical aid stations at major aid stations and the finishing line. Many of the other aid stations will also have additional medics on hand. If you suffer an injury or accident that warrants direct medical attention and you are not able to get to an aid station, there will be a number for the medical director provided before race day. Due to the nature of the course ie. off road, the medics may take some time to reach you, or potentially be out of contact for some time tending to other runners. In an emergency please call both our medics AND 999. If you are injured but able to walk, please make your way to the nearest aid station where there will either be a medic, or the aid station captain will immediately get in touch with medical care. If you suffer a severe injury, encounter someone in serious difficulty or are in any doubt at all please call 999 for emergency ambulance services. If you come across a fallen runner please remain with them until help arrives.


80% of the course is on trail. Trail shoes are advised. There are sections of trail which can be slippery and very muddy in the wet. Please use due care and attention on steep downhill sections and particularly on the stairs at various points on the course.
